PAK Start Screens
MultiFlex PAK Hand-Held Terminal Interface • 33
8.2. PAK Start Screens
When the HHT is plugged into the MultiFlex
board, the HHT display will show the model
type of the MultiFlex (PAK), the CPC part num-
ber, and the firmware revision.
Pressing the DOWN ARROW key from the
start screen displays the address and baud rate
settings as read from the MultiFlex’s addressing
and baud rate DIP switches.
From the DIP Settings screen, pressing the
DOWN ARROW key again will select the first
PAK status screen. You will not be able to view
the start screen or the DIP Settings screen again
without disconnecting and reconnecting the
HHT.
8.3. PAK Status Screens
The eleven PAK Status Screens show the
current readings of all PAK inputs, the states of
all outputs and proofs, and other operating infor-
mation.
By default, the HHT automatically scrolls
through the screens in sequence every 3 seconds.
To freeze the display on the current screen, press
the POINT "." button on the HHT. In this mode,
you can use the UP ARROW and DOWN
ARROW keys to scroll through the status
screens.

Suction.
The current value of the suction pres-
sure input.
Discharge.
The current value of the discharge
pressure input.
Amb 1 Temp.
The current value of ambient
temperature sensor #1.
8.3.2. Status Screen 2
This screen shows the current values of com-
pressor discharge temperature inputs #1 through
#8. The third line of the display shows inputs #1
through #4 from left to right, and the fourth line
of the display shows inputs #5 through #8 from
left to right.
If a sensor input is unused, disconnected, or
there is a break in the wire, "OPE" will be shown
to indicate an open input. If a sensor input is
shorted, its value will be shown as "SHO."
8.3.3. Status Screen 3
Cond TD.
The Cond TD is calculated by sub-
tracting the ambient temperature from the con-
denser’s discharge temperature (calculated by
converting the discharge pressure to tempera-
ture). The Cond TD is compared to the PAK’s
Condenser TD setpoint when controlling the
fans.
Amb 2 Temp.
The current value of the Ambient
Temp sensor #2 (or OPEN if this sensor input is
unused).
